Abstract
A disposable diaper comprising, an absorbent pad assembly having an absorbent pad, and a relatively thin sheet of flexible material covering a surface of the pad. The diaper has a tape fastener comprising, a pressure-sensitive tape strip having a section secured to an outer surface of the sheet in an area at least partially covering the pad. The diaper also has adhesive means directly bonding the sheet to the pad in a region extending from the area to a location spaced from the area in a direction away from forces normally applied to the strip during placement and use of the diaper.
Claims21
A disposable diaper, comprising:
- an absorbent pad assembly having an absorbent pad, and a relatively thin sheet of flexible material covering a surface of said pad;
- a tape fastener comprising, a pressure-sensitive tape strip having a section secured to an outer surface of said sheet in an area at least partially covering said pad, and a securement portion adapted to extend past a side edge of the pad assembly for securing the diaper about an infant;
- and
- adhesive means directly bonding said sheet to said pad surface in an isolated region overlapping a major portion of the area and extending beyond said area to a location spaced from the area in a direction away from forces normally applied to the strip during placement and use of the diaper, said region including a portion extending substantially the width of said tape section in said area and being sufficiently saturated to reinforce the pad adjacent said surface and minimize tearing of the pad assembly in said region.
A disposable diaper, comprising:
- an absorbent pad assembly having an absorbent pad, a fluid pervious top sheet, and a backing sheet of fluid impervious material covering at least a portion of a back surface of the pad and extending around a side edge of the pad;
- a tape fastener comprising, an elongated pressure-sensitive tape strip having a section secured to an outer surface of said backing sheet in an area with at least a substantial portion of said section being located over said pad, and a securement portion adapted to extend past a side edge of the pad assembly for securing the diaper about an infant;
- and
- adhesive means directly bonding said backing sheet to said pad in a region overlapping a major portion of the area and extending beyond said area around said side edge of the pad, said adhesive means being saturated in a sufficient quantity to reinforce the pad and minimize rupture of the backing sheet.
